The paper presents an alternative to scholarship on the distributional politics of finance that emphasizes citizenship‐based claims to new financial rights. To compensate for the dominance of exclusion‐based etiologies of financial marginality in financial geography, I reframe financial exclusion as a problem of financial government—that is, as a problem of conducting the conduct of risky populations without threatening the security and autonomy of financial markets. Drawing on Foucault's distinction between technologies of discipline and security, I describe how barriers to the extension of financial government create tiered processes of financial subject formation. The inchoate “subprime’ financial subject produced is the correlate of a specialized financial governmentality—a homo subprimicus eminently governable by financial means. I close by calling for greater attention to questions regarding the relationship between technologies for valorizing bare life, new systems of financially mediated value extraction, and emerging capitalist class processes.
